The 48-year-old sold wraps of drugs to an undercover police officer while her toddler granddaughter sat in the back.

On other occasions Duffy’s daughter, Megan, 13, was with her when the deals were done.

Duffy and her husband, Edward, 49, both of Standard Road, Croxteth, were jailed for a total of four years.

She pleaded guilty to 14 counts of supplying Class A drugs and was jailed for two years and eight months.

He admitted two charges of being concerned in the supply of illegal drugs and was jailed for 16 months.

Judge William George told them: “Bridget Duffy, you had a greater involvement.

“There is a difference between being caught up in driving a person home from Asda and being asked to divert as your husband did and the role you adopted, which was to be responsible for the actual delivery of drugs to someone you understood to be reliant on drugs.”

They were snared in a police operation that saw officers infiltrate drugs gangs in Croxteth and Norris Green last year.

Michael McCormick, 39, of Utting Avenue, Norris Green, was given a two-year supervision order and told to attend a substance misuse course after admitting two counts of supplying Class A drugs to the undercover officer.

Bridget Duffy’s son Liam Duffy was convicted of the manslaughter of Liam “Smigger” Smith last year.
